The image below is a triangle drawn inside a circle with center O:
A triangle is shown inscribed inside a circle. The leg of the triangle labeled 4 inches passes through the center of the circle, O. The other two legs are labeled as 2 inches and 3 inches.
Which of the following expressions shows the area, in square inches, of the circle?
(π = 3.14)
3.14 ⋅ 2
3.14 ⋅ 3
3.14 ⋅ 22
2 ⋅ 3.14 ⋅ 22

I wish I can help if I remember the formula to find area of a circle. Do you remember?
no lol @Loser66
I need help im so confused !!!!!!!
If you dont know how to find the area of a circle, then you need to review your course material.
um i did and the reason i came on here is for you people to atleast ehlp me understand it . ? @amistre64
Do you remember the formula? You answered, No
Not: I did, not, here it is, nothing. just No.
So, how do we calculate the area of a circle? post your thoughts, and then we can proceed.
goodness i hate math.
this isnt math, its just a formula. formulas are memory stuff, not math perse.
and there is something off in your option, that i agree.
area equals pie r2
oh good, my brain was set on circumference ... i would have gotten it wrong by a simple mistake.
what is our radius?
half of 4 yes.
so pi 22 assuming your paste ate the exponent marker.
and now, this is why you finding the formula was important, I was considering using 2 pi r instead - which was wrong in my head.
so the answer is 3.14 * 2 square
i need help with another question
we both might lol, what is it?
Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck?
what is our current ratio?
what do you mean ?
a ratio is the number of items in one set, compared to the number of items in a different set.
say I have 3 apples and 2 oranges, the current ratio of apple to oranges is: 3:2
i feel so stupid even though i have a a in math lol
15 is required
6 of one, 9 of the other, and 15 total
6 :9 :15 now the ratio stays consistent for any multiple, say k
6k :9k :15k
we want the value of 6k
we know that 15k = 60, since we have a total of 60 cards in the entire deck
what should the value of k be?
